xircom_cb should return NETDEV_TX_BUSY when no descriptors available
Changes in other networking paths uncovered a bug in the xircom_cb driver which made the kernel spew lots of the following error messages: BUG eth1 code -5 qlen 0 It turned out that the driver returned -EIO when there was no descriptor available for sending packets. It should return NETDEV_TX_BUSY instead. This was discussed on the netdev list before, see http://thread.gmane.org/gmane.linux.network/84603 .
